In Django Restframework, how to create user model with profile model?
I am trying to create User with Profile on Serializer's create method. Expected input is (name, email, password). email and password will be used to create User instance and name and user instance itself will be used to create Profile instance. In UserRegisterSerializer, model is User and I defined additional field 'name' since it is not a field of User model. in create method, name is popped from validated data, and user is created with email and password. profile is created with user and name. When I test for creating user, it raise an error message 'AttributeError at /api/users/register/ Got AttributeError when attempting to get a value for field name on serializer UserRegisterSerializer. The serializer field might be named incorrectly and not match any attribute or key on the Users instance. Original exception text was: 'Users' object has no attribute 'name'.' I don't understand it since I didn't attempt to get a value for field name. How should I fix it? What is my mistake? Views.py class UserRegisterAPIView(CreateAPIView): queryset = User.objects.all() serializer_class = UserRegisterSerializer Models.py Users : customized user that has id, email, password etc fields.

How to get display value from Django Choices directly from the declared choice constant?
Lets say I defined a model class from model_utils import Choices class SomeModel(TimeStampedModel): food_choices = Choices( (1, "WATER", "Water"), (2, "BURGER", "Burger"), (3, "BIRYANI", "Biryani") ) food = models.IntegerField(choices=food_choices, default=food_choices.WATER) How do I get the display part while using the choices as a variable? eg.

I know if I create an instance, then I can fetch the display value using .get_food_display() for that instance, but I don’t want that I just want to use it directly from the constant created for Choices, ie food_choices. -

Add a variable inside static tag for Django
